The U77 High End Classic Tube Microphone is GERMAN DESIGNED, GERMAN MADE, IN GERMANY BY HAND with a GERMAN MADE, TRUE M7 Capsule made in BERLIN. some parts and accessories of the U77 are also built by hand in sourrounding areas of Eastern Europe.
The U77's tube is a NOS hand
tested 5703 Raytheon military lamp with extremely low noise and very
long operating life. The parameters are closely related to the
legendary AC701K, however the noise floor is a marked improvement over
the AC701K. The capsule is our exact replica of the M7 utilizing the
Berlin "double ring type" and is built, skinned and tuned by hand in
Berlin by our expert German capsule builder. 
The transformer is hand wound from military materials and manufactured
in small series only. All components utilize point to point wiring and
GAC7 microphone cables from Gotham are used as well as German made Sommer cabling.
The PSU is designed with reference to maximum safety and superior
performance lending itself to extended tube life. All power components
are high-end avoiding the use of any Chinese components.
Included is a solid mahogany box and U47 style shockmount. Each
microphone is measured in our lab on Bruel & Kjaer measurement
machines and frequency response diagram for each pattern is included
with every microphone. Berliner USA is currently designing a custom
metal pop screen which will affix directly to the microphone body.
The vintage style carrying case is elegantly designed and built by hand
utilizing materials such as 600+ denier nylon, Dupont Cordura®, and
high quality brass hardware.
